STAMP-DELIVERY MACHINE.

Specification of Letters Patent.

Application filed December 3, 1920. Serial No. 428,089.

To all whom it may concern.'

Be it known that I, HERMANN THUN, residing at Essen-Ruhr, Germany, a citlzen of the (rerman Republic, have invented a certain new and useful Improvement in Stamp- Delivery Machines, for which I have filedy application in Germany May 8, 1919, of which the following is a specification.

The subject matter of the invention is a stamp delivery machine with a counter which shows direct the value of the stamps delivered.

On the drawing an automatic stamp delivery device is shown as an example of construction of the invention, which contains eight kinds of stamps of different value. On this drawing:

Figure 1 is a plan in diagram of the stamp delivery machine.

Fig. 2 is a lateral sectional view of a detail and Fig. 3 is the front view corresponding to Fi 2.

n a drum A which can rotate about a vertical shaft B, eight rolls C containing the different strips of stamps are rotatably mounted. T-he strips of stamps may only be made up of stamps the value of which 1s di= visible by live without remainder. At' the side of each roll C an arm D is fixed on the drum A and carries a vertical rod D1 rigidly connected with it. The rods D1 are stepped downward to different depths so that stop surfaces Z2 are formed thereon, which lie at different depths for each individual rod D1. These depths are determined by the value of the stamp contained in the corre# sponding stamp roll C and are equal to a unit o, multiplied by the figure whlch results from division of the value of the various stamps byfve (Fig. 2). The rods D1 are so arranged that their stop faces @Z2 can project into the path of a cam e1 provided on a verticallyl slidable rack E guided by two bolts F and F1. The rack E can be slid to such an extent that its cam e1 can come to lie against the deepest stop surface (Z2. Under the action of a tension spring G the rack E lies firmly on the free end of a pvotallyv mounted single arm lever H, which in turn, owing to the actio-n of 'a spring (not shown) which is more powerful than the tension spring G, lies against a pin J. The stroke of thelever H is limited downward by a second pin J1. On a shaft N, mounted in a cylindrical casing M there is fitted outside the casing M a pinion K, with which the rack E meshes. Inside the casing M the shaft N carries an arm P rigidly fixed thereto, on the free end of which a ratchet R is mounted so as to be able to rotate (Fig. 2) and is under the action of a spring Q. l The ratchet R engages in the teeth of a ratchet wheel T which is mounted coaxially with the pinion K in the casing M so as to be resistently rotatable, and has twenty teeth t1. The disposition adopted is ysuch that the ratchet wheel T, when the pinion K rotates clockwise, is made to share in this movement by the ratchet R, but remains stationary when the pinion K rotates in the opposite direction. The ratio of transmission between the rack E and the pinion K is such as to secure that when the ratchet E descends by the amount ofthe unit o the ratchet wheel T is tripped to the extent of one tooth. On its outer periphery the ratchet wheel T carries the ligure 0 and the figures from 5 to 95 divisible, without remainder, by 5, these figures being uniformly distributed and visible through a window m1 provided in the casing M. Adjoining the ratchet wheel T there are mounted so as to be able to rotate loosely on the shaft N, drums provided with figures which are connected with each other and with the ratchet wheel T in the known way by Maltese wheels and which show the hundreds, thousands, etc.

If the stamp delivery machine is required to deliver a stamp for instance to the value of 2O pf., the drum A is turned until the rod D1, corresponding to this value of stamp, is opposite the rack E. If the lever is now pressed downward till it stops against the pin J1 then an arrangement, not shown, and connected with the lever H, actuates the stamp delivery device so that the stamp can be taken out. At the same time the spring G draws the rack E downward until the cam e1 comes to lie against the stop face 032. The rack E then, as is' evident from what has been said above, descends to 4. 'v and, through the agency of the pinion K and the ratchet R, effects a trip movement of the ratchet wheel T of four teeth, i. c., an increase of the figures appearing in the window m1 up to four times ve=20, which corresponds to the value of the stamp taken out. After release of the lever H, this lever, under the action of the spring (not shown), moves upward till it strikes against the pin J and brings back the rack E into its former posi'- tion against the action of the spring G. The result of this movem-ent is a rotation of the pinion K counter-clockwise. Meanwhile the ratchet R slips over the teeth of the ratchet wheel T, the position of Which is therefore not affected by the release of the lever H. Vhen taking out a stamp of the value say of 40 pf., the rack E descends by 8. o and causes a trip movement of the ratchet Wheel T of eight teeth, therefore an increase of the ligure appearing in the windoW m1 by eight times iivezllo, which again corresponds to the value of the stamp taken out. cates the value of the stamps delivered.

lf a stamp delivery device is to be designed in accordance with the invention also containing stamps to the value of 2-.}- and 711i pfennig, the ratchet Wheel must have 100: 2:40 teeth and the unit v Will again be chosen in such a way that when the rack E descends by this unit the ratchet Wheel T is tripped on by one tooth. On its periphery the ratchet `Wheel T carries the ligure O and the figures from 2% to 9711;, divisible Without remainder by 212-.

Claims.

1. The combination Ivvith a stamp delivery machine of a counter, said counter comprising a figure drum provided with figures indicative of the value of stamps delivered, means for rotating said drum, the stamps being carried in rolls,'and means adjacent each roll coperating with said drum operating means for allowing rotation of the drum an amount corresponding to the value of the stamp delivered.

2. A. stamp delivery machine provided with a plurality of stamp rolls in combination with a counter, said counter comprising a drum provided with figures for indirlherefore the counter directly indi- Lasagnay eating the values of the stamps delivered, a rod adjacent each stamp roll, means for operating said drum, said rods coperating With said drum operating means for limiting the amount of movement imparted thereto, corresponding to the value of the stamps delivered.

3. A stamp delivery machine having a plurality of stamp rolls, in combination With a counter, said counter comprising a drum provided Withl figures for indicating the value of the stamps delivered, rods mounted adjacent said stamp rolls, shoulders Jformed on said rods, said shoulders being formed at graduated points Jfrom the ends oi" said rods, a pinion carried by said drum, a rack for operating saidvpinion, the shoulders on said rods coperating with said rack to limit the rotation imparted to said drum, corresponding to the value of the stamp delivered.

l. A stamp delivery machine having a plurality of stamp rolls in combination With a counter, said counter comprising a figure drum, a paWl and ratchet for rotating said drum, a pinion for operating said paWl, a vertical movable rack meshing With said pinion, a rod positioned adjacent each stamped roll, stops formed on said rods, said stops being positoned on said rods at graduated distances from the ends thereof, a stop on said rack bar, the stops on said rods projecting into the path of the stop on the rack bar to limit the amount of rota' tion imparted to Said drum, as and for the purpose described.

The foregoing specification signed at Essen, Germany, this 26th day of July, 1920.
